Petunia plant named ‘Hoobenihime’

ABSTRACT

A  Petunia  variety named ‘Hoobenihime’ particularly distinguished by having red-purple flowers with a dark purple edge and small flower size is disclosed.

Genus and species: Petunia hybrida.

Variety denomination: ‘Hoobenihime’.

BACKGROUND OF THE NEW PLANT

The present invention comprises of a new and distinct cultivar of Petunia, botanically known as Petunia hybrida, and hereinafter referred to by the cultivar name ‘Hoobenihime’. It is characterized by having a purple flower with a dark purple edge and a small flower size. Petunia variety ‘Hoobenihime’ originated from a single plant mutation in Kanagawa, Japan in 2007. The parent was a proprietary Petunia breeding line named ‘Usubenihime’ having a pink flower with a dark pink edge and a small flower size.

In December 2006, the original breeding line ‘Usubenihime’ was vegetatively propagated from plant cuttings. In May 2007, a single plant mutation which had darker colored flowers was discovered in the trial. In November 2007, the selection was vegetatively propagated in Salinas, Calif. from cuttings of the plant mutation. In May 2008, plants of the selection were cultivated and the resulting plants showed the same flower characteristics as the single plant mutation. Plants of the selection were trialed again continuously to check for uniformity.

In April 2009, the selected line was observed to have its distinct characteristics remain uniform and stable. The selected plant line was confirmed to reproduce true to type in successive generations of asexual propagation. The selection was subsequently named ‘Hoobenihime’.

Plant Variety Protection for this variety was applied for in Japan on Aug. 24, 2010. ‘Hoobenihime’ has not been made publicly available more than one year prior to filing of this application

DESCRIPTION OF THE NEW VARIETY

Data was obtained from plants grown 5 months from transplant to 8-inch pots from rooted cuttings in Salinas, Calif., under greenhouse conditions. Plants were pinched once during growth.

The following traits and characteristics describe the new variety. Color references are to The Royal Horticultural Society Colour Chart, 4th edition. Anatomic labels are from The Cambridge Illustrated Glossary of Botanical Terms, by M. Hickey and C. King, Cambridge University Press.

The vegetative     cuttings were propagated in five to six weeks. The base of the     cuttings were dipped for 1 to 2 seconds in a 1:9 solution of Dip 'N     Grow (1 solution: 9 water) root inducing solution immediately prior     to sticking into the cell trays. Cuttings were stuck into plastic     cell trays having 98 cells, and containing a moistened peat     moss-based growing medium. The cuttings were misted with water from     overhead for 10 seconds every 30 minutes until sufficient roots were     formed. Rooted cuttings were transplanted and grown in 20 cm     diameter plastic pots in a glass greenhouse located in Salinas,     Calif. Pots contained a peat moss-based growing medium. Soluble     fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium     was applied once a day or every other day by overhead irrigation.     Pots were top-dressed with a dry, slow release fertilizer containing     20% nitrogen, 10% phosphorus and 18% potassium. The typical average     air temperature was 24° C. -   Stems:     -   -   Color.—RHS 143B (Green).         -   Diameter.—Approximately 2.0 mm.         -   Length.—Approximately 10.0 cm to 12.0 cm.         -   Description.—Pliable; circular cross-section.         -   Pubescence.—Heavy.         -   Pubescence color.—RHS N155A (White). -   Lateral branches:     -   -   Number.—Approximately 8 main basal branches; many secondary             and tertiary branches.         -   Length.—30.0 cm to 32.0 cm.         -   Diameter.—4.0 mm.         -   Internode length.—Approximately 2.5 cm.         -   Color.—RHS 143B (Green).         -   Texture.—Dull. -   Leaves:     -   -   Arrangement.—Alternate.         -   Shape.—Ovate.         -   Apex.—Obtuse.         -   Base.—Attenuate.         -   Margin.—Entire.         -   Attachment.—Petiolate.         -   Surface texture (both surfaces).—Dull, waxy and sticky.         -   Surface pubescence.—Slight.         -   Pubescence color.—RHS N155A (White).         -   Variegation.—Absent.         -   Fragrance.—Absent.         -   Venation.—Pinnate.
